Fraunhofer's 3D printed exploration spiders are intended for use "as an exploratory tool in environments that are too hazardous for humans, or too difficult to get to." They use hydraulic bellows to execute advanced maneuvers, including jumping:
With its long extremities, the spider has a range of ways to get around. Some models can even jump. This is possible using hydraulically operated bellows drives that serve as joints and keep limbs mobile. With no muscles to stretch their legs, these creatures build up high levels of body pressure that they then use to pump fluid into their limbs. Shooting fluid into the legs extends them. “We took this mobility principle and applied it to our bionic, computer-controlled lightweight robot. Its eight legs and body are also fitted with elastic drive bellows that operate pneumatically to bend and extend its artificial limbs,“ explains Dipl.-Ing. Ralf Becker, a scientist at IPA. The components required for locomotion, such as the control unit, valves and compressor pump, are located in the robot‘s body; the body can also carry various measuring devices and sensors, depending on the application at hand. Hinges interoperate with the bellows drives so that the legs can move forward and turn as needed. Diagonally opposed members move simultaneously, too. Bending the front pairs of legs pulls the robotic spider‘s body along, while stretching the rear extremities pushes it.
When game critic Jim Sterling uses video clips of the games he reviews on YouTube, the game companies claim copyright ownership of the video and run ads on Sterling’s reviews. He doesn’t like that because his videos are funded by Patreon and he doesn’t think his audience should have to see ads. So what he […]
Campaigners from Liberty, a civil liberties group, took to the streets of London (and the lobby of the Home Office!) and grabbed peoples’ phones, browsing them while explaining that they just wanted to build a detailed dossier of their lives by looking at their communications, browsing history and location data — mirroring the way that […]
You never know when new projects, ideas or opportunities can drop into your lap at a moment’s notice. That may require you to learn a new programming language like Python. Or maybe you need a primer on 3D game development. Or you might realize you could use a serious brush-up on iOS mobile creation.Point is, […]
Isn’t it about time to stretch what your Mac can do? I mean, you’ve got plenty of great programs now…but don’t you think you could use some new tools to get your creative, analytical and organizational juices really flowing? It’s spring, so we cleaned up a whole bunch of super-cool apps lying around and packaged […]
In the world of app development, there’s no greater arena to find success than with Android users. About 80% of the smartphones in use today worldwide operate on the Android operating system, so if you build a great app that Android users love, you’re an international rock star. You’ll be able to make sure your […]
